I literally didn't even finish watching the Report. I went over to the site thinking this whole online academy was a neat idea, and started finding videos about the topics I need to study for my test next week (pity I only found out about the Academy today). It's 1:56am and I'm studying Biology on the web for free. THIS is what those visionaries imagined the Internet would be one day.
Studying & learning for 'visual learners' has become so much better with mainstream internet use and great videos like this. Thanks for simplifying something which is initially quite confusing:)
Thank you so much for taking the time to make these videos. I am taking an EMT course and have been memorizing all the information so I can pass the test but never really understanding how it works and after watching these videos it is all starting to make sense ^.^
Super helpful video! I sat down to watch the cellular respiration series thinking that I would be cramming for my cell bio exam tomorrow but it turns out that I already knew the stuff,, i just needed a simple and clear expaination and this was it! I don't think many professors know how helpful it is (especially to adhd students like myselft) to just explain things in the simplest terms and expressions. I just love how concise and exact your lessons are. I know it can be good practice to have to use critical thinking skills to reach conclusions about topics like this but i find that style of teaching to be my weakness. anyways thanks a bunch for these great videos! If i wasn't a broke college student i would surely provide a great donation!
Best video on Cellular Respiration 👏🏽 thank you! I finally understand it! For anyone to understand this start by 1. Understand the basic understanding of Enzymes for catalyzing the chemical reactions of life 2. Watch the amoeba sisters on this topic 3. Then come back to this video and everything makes sense 😂😂😂
I love this! This is such an amazing explanation. I've always struggled to understand these concepts and I have ADHD so it's especially difficult for me. But I love this teacher! I plan to watch every video I can! I just can't thank you enough! It's really going to help me with my future career plans. I haven't watched any videos with other teachers yet, so I can't say how well the others do at explaining things, but if I were a teacher I would want to be this good. And if I ever make enough money to do so, I will donate to this organization.
I find that watching videos like this is the happy medium of learning. (So is teaching in a class while writing on the board, if the teacher does it well, i think.) Reading from a textbook is energy-draining and difficult. Listening to a lecture can be boring and you can miss details. But listening *and* reading, looking at the notes and listening to the explanation, is like reading along to an audiobook; it makes a lot of sense, and doesn’t require that much strain or cause confusion. Thank you for all the help. I hope you know you’re a *literal blessing* to us all
Sal, watching your Biology videos saves me a lot time and I actually understand all these subjects better. I'm sure I'll do good in my Biology finals tomorrow because of you. (:
You're the best! I didn't even get what the teacher was talking about I thought I was dumb but NO! I actually am not dumb!!! You're the BEST!!!! You're my teacher now!!!
Thank goodness for this video! My biology teacher makes cellular respiration much more compicated than it needs to be. This video will save me on the test tomorrow!
this is excellent. One of the best videos on youtube. Thorough, precise, and enough detailed information to not only give us the main idea, but not too many stupid little fragments. Thank you so much. My honors bio teacher is 80 years old and doesn't have a clue what he is doing.
I was 9 when this was posted.. wow, I’m now second year university student and completely lost and this video has made me less stressed, only just Little
Thank you for taking the time to actually explain this in a calm manner unlike crashcoarse that just rushes through everything. After this video, I have a better understanding of cellular respiration!
Think of ATP as money. To start your business (glycolysis) you spent 2 dollars (2 ATPs) and at the end of the day made 4 dollars(4 ATPs) therefore you profited 2 dollars (a net of 2 ATPs)
I might be one of the rare ones that isn't here for my midterm! I'm actually studying Biology at university and I tutor highschool students. I wanted an example for an introduction because I wasn't sure how to start... I might just make her watch this video, she won't need me anymore! you're amazing :)
I'm so happy i actually used his videos. I had my midterm today and professor added 3 essays and one of them were on this topic! and 50 multiple choice ... and some true and false.
why do you give these videos for free?? they're so good..u'd be so rich if you cost money for tuitions..the whole world's gonna come and pay you....hi..m shreya from india..can u add some more videos related to medicine studies..I mean higher studies..ryt now m in 10 th year but I would need them for my 11th and 12 grades also..plz!!!!!! awaiting response..thnQ..plz!
May be u are rich enough to pay for each and every online helpful or useful videos. But many people arent. The more the number of viewers the uploader gets the money, so its fair.. If the video is nice and watchable then it is obvious it will have maximum viewers and the uploader get to earn money and the students who are hungry for knowledge gets to lear many new and interesting things.
you can find these videos in khan academy, just search it online cuz its there. its like lessons just like this video and it can vary to a lot of topics too.
Thanks this really helped cause my science teacher didn’t teach us anything like she just gave us notes everyday and most of the time I had no idea what they talked about anyways have a good day and thank you.
38 ATP is how many ATP that is produced in the entire process from 1 glucose, but there are multiple steps that require ATP and only produce ATP under ideal conditions so the NET ATP is closer to 30 ATP. It is calculated as cytosol NADH (NADHc)=1.5 ATP (as it costs an ATP to enter the mitochondria) mitochondria NADH (NADHm)=2.5 ATP GTP=1 ATP FADH2=1.5ATP Glucose = 2ATP+2GTP+2NADHc+8NADHm+2FADH2 = 30 ATP (text books say 36 because they round all the .5 ATPs up and 38 because they dont account for the invested 2ATP.)
+叶靖宇 one molecule of glucose will produce 38 mol of ATP if the NADH produced is transported to the mitochondria via the malate shuttle but if it is transported to the mitochondria via the glycerophosphate shuttle, only 2 mol of ATP will be formed so the net production will be 36 instead of 38
+叶靖宇 Without the Krebs cycle it would produce only 36 but combing the process of the Electron transport chain and the Krebs cycle it creates a total a 38.
Got a 90% on my exam and you cut my study time in half providing me with more study time for other classes. Thanks for the download info as well. You are awesome and very much appreciated for the videos that you make. Thank you.
And I FI-NAL-LY get it! Since I have this years' worst biology teacher who just sits back in his chair letting us figure out what's it's all about, I really really needed this for my test tomorrow!
I want to thank you for doing what your doing here its truely refreshing to see someone take the time to help everybody else out there it shows just how usefull the internet can be keep doing what your doing because it is more than appreciated
Donate people! Even if just $5. This is SO valuable! Especially for those who don't have access to quality education like this. Thank you, Khan Academy, I appreciate your work!
Hi just want to congratulation you on your great work. I am retaking my Anatomy and Physiology exam in 4 weeks. Need lots of this turor work to enable me to pass second time round. I am hard of the hearing get by through wearing hearing Aids. Class was not sufficent for me.. I have lots to do in 4 weeks.....

Anyone watching this before a test😂?
Everyone basically 😂

I got a test in 20 min 😂
I always do this technique
watching this because of finals anyone?
yea its a saviour ofcos
Ha. Im doing this because of a middle school project.
It's easy if you firm a chart in your mind and learn it
Ya mine is tomorrow
me getting confused at all the college test comments because we're studying this in ninth grade
lmao same
Come back in 15 years as a mature age student and see how well you remember it....
trust me.. you wont remember this in four years
I just learned this few days ago and now I already forgot everything

Test tomorrow, I can't stop ✋ procrastinating. I need to focus
I thought Indians didn't procrastinate

It took me like ten different videos but I think I'm finally understanding this!
Thank you so much for taking the time to make these videos. I am taking an EMT course and have been memorizing all the information so I can pass the test but never really understanding how it works and after watching these videos it is all starting to make sense ^.^
I'm doomed. test over this and two chapters Monday for college
I'm doomed. Help!!!! Pllllleeeeeaaasseee!
Katie kelley good luck 👍🍀
I got a higher grade on my most recent bio test. Now to get though the rest of the year
me too
doing this as a 7th grader :/
Thank you so much!!!! Now I really understand cellular respiration! You helped tons! God Bless you!
This professor is the best!!!! I hate online classes but I would rather take his online class than in person because he is just THAT GOOD!

Thank you! I love how you use the colors . You wrote so clearly. Makes it so much better!
this is an honest question...can someone please tell me when i will ever need this, unless i become a biologist
Super nice video, clear, structured and very organized.Thanks for your input.
Sal, watching your Biology videos saves me a lot time and I actually understand all these subjects better. I'm sure I'll do good in my Biology finals tomorrow because of you. (:
You, sir, have always been a life saver! Thank you so much for everything ❤️
thank you so much for these videos, my ap bio class is basically a self study class and ive really been struggling because of that
Thank you so much for making these videos!!!They'll help me a lot!!!
You're the best! I didn't even get what the teacher was talking about I thought I was dumb but NO! I actually am not dumb!!! You're the BEST!!!! You're my teacher now!!!
wow..
This is the BIGGEST educational video archive i've ever seen
I love how simplified this is... Makes me feel smart (even though Biology is my worst subject)
Wow, thank you so much. You helped answered many of my questions!!
aaaaaaaand i'm failing
lol XD I feel you. This is painful.
Thank goodness for this video! My biology teacher makes cellular respiration much more compicated than it needs to be. This video will save me on the test tomorrow!
Where can I get that amazing black board with colors online? What do I google? I wanna make educational videos too and I wanna use this. Help anyone?
I've understood everything this semester except respiration and this has been a really good review to help clarify before exams. Subscribe!
it helped me a lot in a scinence contest i got 1st
Khan Academy is so fantastic...i haven't been exposed to such useful educational material in decades and it is getting my mind working again
Very well explained, thank you.
This is the BEST educational instruction in Bio i have EVERRR seen!!
Great video.......helped a lot.....
your teacher knows Khan can teach this better than they can. Thank your teacher.
i love khan academyy
He's amusing and teaches it correctly. Trade places with my teacher? PLEASE!?
I think it should be net 30 ATP (eukaryotes ) and 32 ATP (prokaryotes) from current understanding/research.
Alex Wang thanks
I do not know what i would do without this videos!!
i have my SAT biology subject test tomorrow and i'm fucked to say the least
Yasna Ali good luck
Nicole Hartson hah thanks it wasn't too bad but i'm definitely not getting a good score

your not the only one.... Now I'm just gonna post random questions off a Prof 2 algebra questions
Good for you, better than wasting your time on social media or videogames.
xeztan by I want to travel

Sal is God sent I swear, I have a test on this in 2 days and my teacher didn’t give enough info
Its FADH2 not FADH, nice video thank you :)
Thank you for taking the time to actually explain this in a calm manner unlike crashcoarse that just rushes through everything. After this video, I have a better understanding of cellular respiration!
what happened to the oxidation of pyruvate after Glycolysis?????!!!!
+tet o I believe those are the two carbon backbones he was referring to at the top under glycolysis
This is a great video, and I'm even more impressed by how well he writes using the cursor.
Glycolysis needs 2 ATP's, to generate 4 ATP's so on a net bases generates 2 ATP's??? wtf is that
ATP is energy.
Think of ATP as money. To start your business (glycolysis) you spent 2 dollars (2 ATPs) and at the end of the day made 4 dollars(4 ATPs) therefore you profited 2 dollars (a net of 2 ATPs)
Jennifer Felix that was a good one

How old are you guys? I would like to see the age variation of the people who watch these videos.
Esteban I'm 11
I am 14 and I am going to fail my test... badly.
14
Esteban 15 but in grade 11th and most likely flunking my test too lmao

Doesn't it produce 36 ATP?
No 38

+叶靖宇 Without the Krebs cycle it would produce only 36 but combing the process of the Electron transport chain and the Krebs cycle it creates a total a 38.
On school tests (EOCs) it says it gives 36 instead of 38 so teachers say it's 36 instead of 38
You realize you save lives right? Thanks a lot you need awards for this (I nominate you for the Nobel Peace Prize)
I thought you did math!?
Drakkona Durab Seriously, he does everything!
thank god for this! i seriously am more confident about my test i have in 30 minutes!
he gets kind of off topic and is super repetitive
he is just trying to be very clear cos not everyone is like you, intelligent -_-
i dont think so.....his explanation is very good tho....

It's 2023 and I'm.studying for Biochemistry exams
This is so helpful
I actually understand this now. Even crash course and Bozeman couldn’t help me on cellular respiration.
you have no idea how many people you've saved, i love you
I have a good teacher but the way you explained it makes a lot more sense.

Amongst all the videos I watched on yt about Cellular Resporation, I can understand this one better. Thank you so much for this 💗💗💗
You're helping my Biology raise from B to A. Thanks
Thank you, THANK YOU for subtitles. I hate it when I have to guess what people are saying, which would be especially difficult for this video.

presentation in two hours he most defiantly saved me.
khanacademy rocks, dude you just make rvrything a lot simpler to understand.
I depended on this man in 8th grade for math and i depend on him now as a junior in college. some things never change
yay for using this to study for my final the day before
I now have a clear understanding of what pyruvate is. Thank you.
Dude I have to take IB bio right now, and I hate it with all my heart, but watching khan academy makes it all fun, and easier to learn
This is an awsome video, I understand cellular resp., glycolysis ,kreb's cycle and fermenetaion now. Thank you so much.
Genius! Wherever I go in my studies, THE SAL has been there before, and is ready to expalin astounding!
Donate people! Even if just $5. This is SO valuable! Especially for those who don't have access to quality education like this. Thank you, Khan Academy, I appreciate your work!
your the best man. you've taught me so much its not even funny.
seriously, you are my savior.
i dont unterstand English so much but this video really help me about Biology :)
Thank you so much !!!
this made me understand cellular respiration much better,THANK YOU
THank you so much!!! I have a quiz and i knew nothing but this helps soooo much :)
This is so much easier I understand than my professors lecture! I loved the word origins that helped so much
It's not 38 ATPs per mole of glucose. It is 2.29 x 10^25 ATPs per mole. We get 38 ATPs per molecule of glucose.
